Let's solve each part of the question step-by-step:
Part 1: Find the Sum We need to add four numbers: 879834, 57813, 1245, and 888888.
[ \begin{align*} 879834 \
57813 \
1245 \
888888 \ \hline 1824780 \ \end{align*} ] So, the sum is 1 , 824 , 780 .
Part 2: Find the Difference Now, we will subtract 7,763,599 from 18,890,000.
[ \begin{align*} 18890000 \
7763599 \ \hline 11126401 \ \end{align*} ] Thus, the difference is 11 , 126 , 401 .
Q2(a): Find the Quotient and Remainder Let's divide 23,412 by 12.
First, perform the division:
23412 ÷ 12 = 1951 remainder 0 .
Thus, the quotient is 1 , 951 and the remainder is 0 .
Q2(b): Find the Product Finally, we multiply 54,321 by 321.
54321 × 321 = 17481341
Hence, the product is 17 , 481 , 341 .
